Which of the following is an example of a reverse transcriptase?

Telomerase reverse transcriptase (abbreted to TE, or hTE in humans) is a catalytic subunit of the enzyme telomerase, which, together with the telomerase RNA component (TERC), comprises the most impoant unit of the telomerase complex. Telomerases are pa of a distinct subgroup of RNA-dependent polymerases. Telomerase lengthens telomeres in DNA strands, thereby allowing senescent cells that would otherwise become postmitotic and undergo apoptosis to exceed the Hayflick limit and become potentially immoal, as is often the case with cancerous cells. To be specific, TE is responsible for catalyzing the addition of nucleotides in a TTAGGG sequence to the ends of a chromosome's telomeres. This addition of repetitive DNA sequences prevents degradation of the chromosomal ends following multiple rounds of replication.

Tetralogy of Fallot (TOF) is a cardiac anomaly that refers to a combination of four related hea defects that commonly occur together. The four defects are: Ventricular septal defect (VSD) Tetralogy of Fallot results in low oxygenation of blood. This is due to: Mixing of oxygenated and deoxygenated blood in the left ventricle the ventricular septal defect (VSD) Preferential flow of the mixed blood from both ventricles through the aoa because of the obstruction to flow through the pulmonary valve. This is known as a right-to-left shunt. Infants with TOF -a cyanotic hea disease- have low blood oxygen saturation.Blood oxygenation varies greatly from one patient to another depending on the severity of the anatomic defects.Typical ranges vary from 60% to around 90%.[Depending on the degree of obstruction, symptoms vary from no cyanosis or mild cyanosis to profound cyanosis at bih.If the baby is not cyanotic then it is sometimes referred to as a "pink tet".Other symptoms include a hea murmur which may range from almost imperceptible to very loud, difficulty in feeding, failure to gain weight, retarded growth and physical development, labored breathing (dyspnea) on exeion, clubbing of the fingers and toes, and polycythemiaThe baby may turn blue with breast feeding or crying.

Which is true about Klebsiella infections?

Predisposing factors for Klebsiella .............. Klebsiella and the related Serratia and Enterobacter are the most impoant enteric organisms other than E. coli to infect humans. Although respiratory disease is impoant (Klebsiella accounts for 1 % or less of community-acquired pneumonia), most clinical isolates now come from the urinary tract. All three genera are impoant pulmonary nosocomial pathogens. However, merely finding these organisms growing in the sputum of a very ill hospitalized patient does not necessarily implicate the bacteria as pathogenic in that paicular circumstance and may indicate colonization rather than infection. Clinical context and procurement of the sample in a sterile fashion (transtracheal aspiration, bronchoscopy) will aid in the diagnosis Chronic alcoholics, diabetics, and those with chronic lung disease are at increased risk for Klebsiella pneumonia, a difficult disease to treat because of the frequency of suppurative complications (empyema and abscess) with the associated requirement for prolonged (>2 weeks) therapy.

Most clinical isolates are obtained from the respiratory tract.

Predisposing factors for Klebsiella pneumonia include alcoholism, diabetes mellitus

Klebsiella is closely related to Pseudomonas.

Detecting Klebsiella growth from a sputum culture obtained from an intubated patient mandates treat ment with an aminoglycoside or a third-generation cephalosporin.

DTPA A renal scan involves the use of radioactive material to examine your kidneys and assess their function. A renal scan is also known as a renal scintigraphy, renal imaging, or a renogram. During this procedure, a technician injects a radioactive material called a radioisotope into your vein. The radioisotope releases gamma rays. A gamma camera or scanner can detect gamma rays from outside your body. The gamma camera scans the kidney area. It tracks the radioisotope and measures how the kidneys process it. The camera also works with a computer to create images. These images detail the structure and functioning of the kidneys based on how they interact with the radioisotope. Images from a renal scan can show both structural and functional abnormalities. This helps doctors diagnose a kidney problem in its earlier stages without invasive techniques or surgery Ref Harrison20th edition pg 223

A Patient presented with Hypokalemia, Severe Hypertension, and Metabolic Alkalosis. The diagnosis is

(A) Liddle syndrome[?]Liddle's Syndrome: Autosomal dominant & is characterized by activating mutation of collecting duct Na+ channel with enhanced sodium reabsorption.oLow renin, low aldosterone levels.oClinical picture mimics Primary Hyperaldosteronism: Hypertension, Hypokalemia & Alkalosis.oIncreased activity of the Epithelial Sodium Channel (E-Na Ch):-Activating kidneys to excrete potassium retaining excessive sodium & water, leading to hypertension.-Classically manifest severe hypertension with hypokalemia, unresponsive to spironolactone yet sensitive to amiloride.oHypertension & hypokalemia are, however, variable aspects of the Liddle's phenotype; more consistent features include a blunted aldosteirone response to ACTH & reduced urinary aldosterone excretion.oIt is a 'gain of function' mutation in the gene encoding ENaC of the collecting tubule resulting in autonomous function of these channel without the influence of aldosterone.oCan be differentiated from Primary Hyperaldosteronism by normal Na+ level and low aldosterone and reninOther OptionsCONGENITAL HYPOKALEMIA ASSOCIATED SYNDROMES[?]Bartter's Syndrome (BS):-Loss of the transport functions of the TALH nephron segments causes hereditary hypokalemic alkalosis.-Typically suffer from polyuria & polydipsia, due to the reduction in renal concentrating ability. May have an increase in urinary calcium excretion & 20% are hypomagnesemia-Marked activation of the renin-angiotensin-aldosterone axis.-Antenatal patients suffer from marked electrolyte wasting, polyhydramnios, and hypercalciuria with nephrocalcinosis; renal prostaglandin synthesis and excretion are significantly increased, accounting for much of the systemic symptoms.-Presence of five disease genes for BS, all of them functioning in some aspect of regulated Na+,K+ & Cl- transport by the TALH.[?]Gitelman's Syndrome (GS):-Loss of the transport functions of the DCT nephron segments causes hereditary hypokalemic alkalosis.-Genetically homogeneous, caused almost exclusively by loss-of-function mutations in thiazide-sensitive Na+-Cl- co transporter of DCT.-Uniformly hypomagnesemic & exhibit marked hypocalciuria, rather than the hypercalciuria typically seen in BS; urinary calcium excretion is thus a critical diagnostic test in GS.-May suffer from chondrocalcinosis, an abnormal deposition of Calcium Pyrophosphate Dihydrate (CPPD) in joint cartilage.[?]Distal Renal Tubular Acidosis:-Defects in multiple renal tubular transport pathways are associated with hypokalemia.-Loss-of-function mutations in subunits of the acidifying-H+-ATPase in alpha-intercalated cells cause hypokalemic distal renal tubular acidosis, as do many acquired disorders of the distal nephron.[?]Cushing's Syndrome:-Hypokalemia may also occur with systemic increasing in glucocorticoids.-Increase in pituitary ACTH incidence of hypokalemia is only 10%, whereas, 60-100% in patients with ectopic secretion of ACTH.

Scabies is caused by a small mite that burrows into the skin. The disease is best described by which one of the following statements?

Sarcoptes scabiei is a small mite that burrows into human skin. Itching is significant, and a vesicular eruption, which often becomes secondarily infected with bacteria, develops. Diagnosis is made by microscopic detection of the mites. Gamma benzene hexachloride (Kwell), a topical insecticide, is an effective treatment for scabies. A number of etiologic agents have been proposed for Kawasaki's disease (KD), among them mites, but there is no evidence that mites either cause or are vectors of KD.

It is caused by a species of Sarcoptes

Secondary bacterial infection is rare

It is synonymous with Kawasaki's syndrome

It is best diagnosed by biopsy of the inflammatory region around the mite bite

Where is bruit heard in thyroid gland

Thrill is felt in the upper pole of the thyroid and also bruit on auscultation. It is because in the upper pole, superior thyroid aery enters the gland superficially and so thrill and bruit can easily be felt. In the lower pole inferior thyroid aery enters the gland from deeper plane and so thrill cannot be felt. Reference: SRB's Manual of Surgery, 6th Edition, page no = 463.

A 45 year old man presents to a physician with back pain and facial pain. Physical examination demonstrates coarse facial features and kyphosis. Laboratory examination is remarkable for elevated alkaline phosphatase. .X-ray studies demonstrate skull thickening with narrowing of foramina, and bowing of the femur and tibia. Bone biopsy reveals a mosaic pattern of bone spicules with prominent osteoid seams. Which of the following neoplasms occurs at an increased frequency in patients with this disorder?

The phrase "mosaic pattern" of newly formed woven bone is a specific tip-off for Paget's disease of bone, and is not seen in other bone conditions. The clinical and radiologic presentation are typical; an increased hat size may also be a clue. In its early stages, Paget's disease is characterised by osteolysis, producing patchwork areas of bone resorption with bizarre, large osteoclasts. In the middle stage of the disease, secondary osteoblastic activity compensates with new bone formation, producing the mosaic pattern. In late Paget's, the bones are dense and osteosclerotic. Paget's disease is suspected to be related to prior viral infection, but the cause remains mysterious. Complications include myelophthisic anemia, high output cardiac failure, pain secondary to nerve compression, deformities secondary to skeletal changes, and in about 1% of patients, osteosarcoma or other sarcoma, typically involving the jaw, pelvis, or femur. An increased incidence of astrocytomas is associated with tuberous sclerosis.Hodgkin's lymphoma is usually a disease of young adults, although older patients may have the lymphocyte-depleted form.Meningiomas are mostly benign tumors that affect adults, especially females. There may be an association with breast cancer, possibly related to high estrogen states. Ref: Wyatt C., Butterwoh IV J.F., Moos P.J., Mackey D.C., Brown T.G. (2008). Chapter 19.

Pubic symphysis is which type of joint

Primary cailaginous joints Known as "synchondroses". These bones are connected by hyaline cailage and sometimes occur between ossification centers.This cailage may ossify with age.Examples in humans are the "growth plates" between ossification centers in long bones. These joints here allow for only a little movement, such as in the spine or ribs.Secondary cailaginous joints Known as "symphysis". Fibrocailaginous and hyaline joints, usually occurring in the midlineExamples in human anatomy would be the manubriosternal joint (between the manubrium and the sternum), interveebral discs, and the pubic symphysis.

Cocaine is sympathomimetic and thus causes vasoconstriction. Cocaine is a local anesthetic with potential for abuse. It produces euphoria by inhibiting the uptake of catecholamines in the CNS, especially dopamine. Because of its abuse potential, cocaine is listed as a schedule II controlled substance by the U.S. Drug Enforcement Agency. Because of its abuse liability and high toxicity, cocaine use is limited to topical anesthesia of the upper respiratory tract. It is available as 1%, 4% and 10% solutions for topical use.

Every AMA has a specific effect on selected microorganisms. Depending on the drug pair as well as the organism involved, either synergism (supra-additive effect), additive action, indifference or antagonism may be observed when two AMAs belonging to different classes are used together Every combination is unique; the same drugs may be synergistic for one organism but antagonistic for another. However, general guidelines are: (a) Two bacteriostatic agents are often additive, rarely synergistic,i.e. combination of tetracyclines, chloramphenicol, erythromycin, etc. (b) Two bactericidal drugs are frequently additive and sometime synergistic if the organism is sensitive to both, e.g.: * Penicillin/ ampicillin + streptomycin/ gentamicin or vancomycin + gentamicin for enterococcal SABE.

A patient undergoes a total gastrectomy because of a proximally located gastric cancer. After the surgery, which of the following digestive enzymes will be produced in inadequate amounts?

Pepsin is secreted (in an inactive or zymogen form as pepsinogen) by the chief cells of the stomach. Pepsinogen is activated by contact with stomach acid. Although protein digestion usually begins with the actions of hydrochloric acid and pepsin, pancreatic enzymes complete the job as the food passes into the small intestine. Amylases hydrolyze 1->4 glycosidic linkages of starches to produce oligosaccharides, maltose, maltotriose, and limit dextrins. These enzymes are produced by the pancreas and salivary glands. Chymotrypsin is a proteolytic enzyme released by the pancreas as the inactive proenzyme, chymotrypsinogen. Lipases are mostly released by the pancreas, and serve to digest various lipids, including triacylglycerols. Ref: Barrett K.E., Barman S.M., Boitano S., Brooks H.L. (2012). Chapter 25.

Reverse cholesterol transpo is mediated by ?

Ans. is 'a' i.e., HDLReverse cholesterol transpoAll nucleated cells in different tissues synthesize cholesterol, but the excretion of cholesterol is mainly by liver in the bile or by enterocytes in gut lumen.So, cholesterol must be transpoed from peripheral tissue to liver for excretion.o This is facilitated by HDL and is called reverse cholesterol transpo because it transpos the cholesterol in reverse direction to that is transpoed from liver to peripheral tissues through VLDL LDL cycle. Processo HDL is synthesized in liver and small intestine.o Nascent HDL contain phospholipids and unesterified cholesterol and Apo-A, C, E.This nascent HDL is secreted into circulation where it acquires additional unesterified cholesterol from peripheral tissues.o Within the HDL paicle, the cholesterol is esterified by lecithin - cholesterol acetyltransferase (LCAT) to form cholesteryl ester and additional lipid are transpoed to HDL from VLDL and chylomicrons.o There are two pathway by which this cholesterol is transpoed to liver.

All of the following are features of Goodpasture syndrome, except:

Goodpasture syndrome Uncommon autoimmune disease in which kidney and lung injury are caused by circulating autoantibodies. Most common in 2nd & 3rd decades of life. Anti-GBM antibody-mediated disease Goodpasture syndrome applies to the 40% to 60% of patients with these autoantibodies who develop pulmonary hemorrhage in addition to renal disease. Characterized by linear deposits of IgG and, in many cases, C3 in the GBM. The antigen common to the alveoli and GBM is a peptide within the noncollagenous poion of the a3 chain of collagen type IV (COL4A3).

systematic sensitization is used in

SYSTEMATIC DESENSITIZATION JOSEPH WOLPE Joseph Wolpe gave the concept of systematic desensitization This is a treatment used in phobia In phobia there is a conditioned fear response to aversive neutral stimulus and avoidance of that response leads to phobia Whenever there is a fear response there is stimulation of sympathetic system In that case stimulation of parasympathetic system by relaxation there is reduction in anxiety First step is to make a step ladder which are arranged based on the severity Then is go step by step and along with doing applied relaxation Slowly the the sympathetic system is reduced The patient will be able to approach stimulus without anxiety Ref. kaplon and sadock, synopsis of psychiatry, 11 th edition, pg no. 845

True about specificity-

Ans. is 'c' Le., True negative o When a screening test is used to diagnose a disease, the test oucome can be positive (diseased) or negative (healthy), while the actual health status of the person may be different,o In that settingi) True positive-Diseased people correctly diagnosed as diseased.ii) False positive-Healthy people wrongly identified as diseased.iii) Tme negative-Healthy people correctly identified as healthy.iv) False negative-Diseased people wrongly identified as healthy.o There are two major statistical measures for the validity of a screening test: -i) Sensitivityii) SpecificitySensitivityo It is the ability of a test to identify correctly all those who have the disease, i.e., true positive.o In other words sensitivity measures the precentage of sick people who are identified as having disease,o For example if a test is 90% sensitive, that means out of 100 diseased people, it will diagnose 90 (90% of diseased people will be diagnosed). Remaining 10% will be wrongly indentified as not having the disease, i.e., false negative.Specificityo It is the ability of a test to identify correctly those who do not have the disease i.e., true negativeo In other words specificity measures the percentage of well people who are identified as not having the disease,o For example, a 90 percent specificity' means that 90% of nondiseased people will be identified as not having the disease. The remaining 10% will be wrongly classified as diseased, i.e., false positive.

Saroj, a 32 year old female, from rural background presented with a h/o chronic tobacco chewing since 14 year of age. Now she has difficulty in opening her mouth. On oral examination, no ulcers are seen - Most probable diagnosis is -

Ans. is 'a' ie. Submucous oral fibrosis " Submucous oral fibrosis is a progressive ds. in which fibrous bands form beneath the oral mucosa. These bands progressively contract so that ultimately mouth opening is severly limited. Tongue movements may also be limited. This conditon is almost entirely confined to Asians. Histologically it is characterized by juxtaepithelial fibrosis with atrophy or hyperplasia of the overlying epithelium which also shows areas of epithelial dysplasias. The etiology is abscure. Hypersensitivity to chilli ; betel nut, tobacco and vitamin deficiencies have been implicated. The scar bands of submucous fibrosis, which result in difficulty in opening can be treated either by intralesional injection of steroids or by surgical excision and grafting, but this has little effect in preventing the onset of squamous cell Ca in the generally atrophic oral mucosa (Submucous oral fibrosis is a precancerous conditon for squamons cell Ca)."- Bailey & Love
